Toallw homitmayconcem: 7 Be it kno'wnthatl, Fnemmcx Hus,

a citizen of the United Sta at Pittsburgh in the countyv of. eghen and State of 'l cnnsylvania; have invente new and usetul Improvementsm Water-Cooling Towers, of which cation.

My invention relates to apparatus for coolinfi water or other liquid.

he .object or this invention is to provide a simple, cheap, and'eflicient 'ap' aratus by verted into. 'a finely which liquid may be cooled'by eing condivided state and by causing a natural or. forced draft of air to This invention also provides a novel means for causing the fluid to be finely divid d. Other objects will api a being shown son for whom it may' pear hereinafter. H

Referring to the accompanying drawings, Figure 1 isa front elevation of a cooling tower embodying'the principles of the present invention, portions being broken away; Fi' 2 a horizontal section, on'an enlarge see c, of a portion of-the said invention the section being taken on the line 2--2, Fig. 1, parts being shown in plan; Fig, 3, a perspective view'sho'wing a portion of the outer face and the sides of one of the louvers which I employ; Fig.4, a cross-section on an enlarged scale showing a portion of the P taken on the line 4-4, 2, the sprayers side elevation; Fig. 5, a section of one o the sprayer devices whichI emplo with. the an m; Fig. 6, a section of a m cation 0 myspraying device; an Fig. .7, ade'tail view showing a portion of oile of the front louvers. Fig. 8 is avertical: sec onshowinga. second modification of myyinvention, and view oiFigi I hail, myuoooler sides an ends, but the shape thereof may be varied to snitthe preference of the pershown the cooler having foarfisupe chambers a, b a, d; Thesides of each chammade :up of louvers 1e fitted vertical] stud the /ends 0 the the beams or into recesses 1n the strips -f arranged between chambers and conn to horizontal members 9 which have their ends connected to the corner 'h.

The louvers on-all side's, exec one, of

the cooler have the slats 1' preterab the following isa specifi-i the pan.

On the front side I make the slats of the louvers rotatable on pivots k at their ends so that these louvers may be .open or closed well known type of house blinds or shutters employingrotatable slats operated by .a vertical bar j by which all the slats in the edges of the s ats. The slats z of each of thefront louvers are pivotally connected to a vertical bar 7', by which all the slats in the louver may be simultaneously rotated on their end Eivots k.

Prefera ly one of the front louvers for each chamber is a door or in a door which may be swung on hinges, as l, to permit an attendant to enter the several chambers.

like the The hinges are preferably -arranged so'as to allow these louvers to swing inwardly.

The upper chamber a has the pan m which closes its upper ber of. downwardly tapering n are suspended Each tube (Fig. 5) base. short distance below its lower end the convex water-spreader or deflector 72 secured on the lower end of the rod or stem q which exthrough the tube n secured rigidly to'the I tendsdown centrally and has its upper end cross-piece r secured to the tube. The spreader stem q may, as shown on Fig. 6, havethe-ring aat .itsll per end to hold the spreader at the selecter distance below the tube 1L This stem has t to hold the stem centrally inthe tube. By inserting a finger in, the ring a the stem and spreader'may be moved up and down (1 to" dislodge any-matter which may be on the spider or spreader.

The water, falls from the sprayer tubes n u' n the convex s readers p by which it is famed into exceedingly thin in'verted'bowL 1 like bodies, which break at their edges into a very fine spray. The. front louvers all elowhthe'fans cause urto pan tion of the next lower chamber 7).

the side and rear louvers and through the falling spray whereby the water which has I been cooled by its expansion into spray is still further cooled by the currents of air. The air exhausted from the chambers by the fans carries a large amount of heat from the chambers, thereby causing the water condensed from the spray to be cooler than it would be without the fans. The water becomes successively cooler as it falls from the several pans. The number of pans will vary according to the degree of cooling required.

.The front louvers may all be open and the fans allowed to remain still, and natural draft be relied on to cool the falling spra when the air is sufiicientlv cool and has sat icient force to cause dra ts to pass through the cooler.

Referring now to 8 and 9, I. show a section of the top chamber a, and a e chambers are substantially alike so that I will describe chamber a only, which is in the form of a. frustum of a pyramid, the louvers 6' being secured between the adjacent inclined studding 5:, or between adjacent studding k and posts It. The upper pan m is supported at the top of the chamber a andis provided with the spraying devices 11, having the spreaders 7). The pan m" is placed at the bottom of. the chamber a and preferably extends to the inner faces of the louvers.

The chamber 7) is immediately below the Clltlll'lb QI a. The bottom of the chamber a exte'fids horizontally at all sides beyond the upper end of the chamber 7/. The spraying devices 11, are put in only the portion of the pan m" which lies directly over the space inclosed by the upper end of the chamber m". The apparatus shown in Figs. 8 and 9 obviously prevents more of the spray from being blown out of the chambers by a.

strong wind than the apparatus shown in Figs. 1 and 2 because of the increasing size of the chamber downwardly. The spray fallin from the upper pan can travel con sidera )ly laterally and still fall into the next lower pan where the louvers or side walls of the apparatus are inclined as shown on Figs.

8 and 9. I. have shown F i s. 8 and 9 with out fans but they obvious y may be used. It will be understood that an ber of chambers like a and b may be superposed.

I claim I. In a liquid cooling tower, a plurality of superposed chambers, some of the sides of the ciambers being provided with louvers, air exhausting means at one of the sides of each chamber, a liquid-receiving pan at the top of each chambcr,-and sprayer de vices in the bottom of each pan.

In a liquid cooling tower, a plurality of superposed chambers, some of the sides of the chambers being provided with louvers and the louvers on one of the sides being losable, air exhausting means at a side having a closable louver, a liquidreceiving pan at the upper end of each of the chambers, andmeans for converting the liquid into spray as it falls from the pans.

3. In a liquid cooler, a plurality of superposed chambers, each in the form of a has tum with its smaller end up, downwardly desired numand inwardly inclinedlouvers on the sides 4 FREDERICK W. HAAS.
